Abstract

The invention discloses a traffic signal lamp control method, device and system, and the method comprises the steps: detecting whether the vehicle passing condition of a first detection region and / ora second detection region of a target lane meets a preset condition or not after the initial green light stage of a signal lamp of the target lane is finished; wherein the target lane comprises a detection blind area, a first detection area and a second detection area which are sequentially arranged from a vehicle line in the direction opposite to the vehicle driving direction, and the vehicle passing conditions of the first detection area and the second detection area are detected through arranged detection equipment; if the preset condition is met, controlling the signal lamp to enter a green flash countdown stage; and if the preset condition is not met, controlling the signal lamp to enter a green light prolonging stage. Through the above mode, the detection precision of the traffic condition can be improved, maintenance is convenient, the green light duration of the traffic signal lamp can be dynamically adjusted in combination with the traffic condition, and traffic jam is avoided.

Description

technical field

[0001] The present application relates to the technical field of traffic management, in particular to a control method, control device and control system for traffic signal lights. Background technique

[0002] A traffic signal light is a signal light for directing traffic operation, and generally consists of a red light, a green light, and a yellow light. A red light means no access, a green light means permission to pass, and a yellow light means a warning.

[0003] In the prior art, the phase switching (ie switching between red light, green light, and yellow light) of traffic signal lights is relatively fixed, generally at preset time intervals. For example, "red light for 30 seconds โ†’ green light for 20 seconds โ†’ green light flashes for 5 seconds โ†’ yellow light for 3 seconds", and so on. However, in practical applications, for different time periods (such as morning rush hour), different festivals, or special circumstances, the traffic flow will have a ...
